What the USDA Doesn’t Want You to Know About Antibiotics and Factory Farms

Here is a document the USDA doesn’t want you to see. It’s what the agency calls a “technical review”—nothing more than a USDA-contracted researcher’s simple, blunt summary of recent academic findings on the growing problem of antibiotic-resistant infections and their link with factory animal farms. The topic is a serious one. A single antibiotic-resistant pathogen, MRSA—just one of many now circulating among Americans—now claims more lives each year than AIDS.

Back in June, the USDA put the review up on its National Agricultural Library website. Soon after, a Dow Jones story quoted a USDA official who declared it to be based on “reputed, scientific, peer-reviewed, and scholarly journals.” She added that the report should not be seen as a “representation of the official position of USDA.” That’s fair enough—the review was designed to sum up the state of science on antibiotic resistance and factory farms, not the USDA’s position on the matter.

But around the same time, the agency added an odd disclaimer to the top of the document: “This review has not been peer reviewed. The views expressed in this publication do not necessarily reflect the views of the United States Department of Agriculture.” And last Friday, the document (original link) vanished without comment from the agency’s website. The only way to see the document now is through the above-linked cached version supplied to me by the Union of Concerned Scientists.

What gives? Why is the USDA suppressing a review that assembles research from “reputed, scientific, peer-reviewed, and scholarly journals”?

To understand the USDA’s quashing of a report it had earlier commissioned, published, and praised, you first have to understand a key aspect of industrial-scale meat production. You see, keeping animals alive and growing fast under cramped, unsanitary conditions is tricky business. One of the industry’s tried-and-true tactics is low-level, daily doses of antibiotics. The practice helps keep infections down, at least in the short term, and, for reasons no one really understands, it pushes animals to fatten to slaughter weight faster.
